UO2[RC(C4H2N)2]2(L) (L = THF (4R-THF); DMAP (4R-DMAP)) (R = tolyl, p-OMe-C6H4, mesityl, ferrocenyl). The THF adducts, 4R-THF, are unstable in aromatic and nonpolar solvents and rapidly decompose to 2 and an intractable uranium-containing solid. On the other hand, the DMAP adducts, 4R-DMAP, are indefinitely stable in solution. The solid-state structures of 4R-THF and 4R-DMAP reveal distorted trigonal bipyramidal
使用一种改进的,无色谱- dipyrrin合成中,α,β -未取代的dipyrrins [RC(C 4 H ^ 2 N)2 H](2)(R =甲苯基(2甲苯基升),p -OMe-C 6 H ^ 4(2 ans),三苯甲基(2 mes),二茂铁基(2 Fc))的分离效果良好,收率很高。用Na [N(SiMe 3)2 ]对2进行质子化,得到碱金属盐[Na(DME)n ] [RC(C 4 H 2 N)2](3),其与UO 2 Cl 2(THF)3反应,得到双(双吡啶)呋喃基双氧铀UO 2 [RC(C 4 H 2 N)2 ] 2(L)(L = THF(4 R -THF) ; DMAP(4 - [R -DMAP))(R =甲苯基,p -OMe-C 6 H ^ 4,三甲苯基,二茂铁基)。THF加合物4 R -THF在芳族和非极性溶剂中不稳定,并迅速分解为2和难处理的含铀固体。另一方面,DMAP加合物4
